KALAMAZOO, MI – It appears a
domestic dispute sparked the fatal beating of Luke Vincent early Sunday morning at a home in Kalamazoo's Vine Neighborhood.

Brian Peterson, who was arrested as a suspect, overheard
Vincent having an argument with his girlfriend in the living room of a house in the 700 block of Cedar Street, according to
testimony of a Kalamazoo Department of Public Safety police officer during an
arrest warrant hearing Tuesday.

Witnesses told police they saw Peterson pick up a dumbbell and
enter the living room. Vincent was soon after found on the floor bleeding profusely
from the head, according to testimony.

Preliminary autopsy results show Vincent, 24, died from blunt
force trauma to the head. Peterson admitted to police that the dumbbell was
his, but denied beating Vincent, the officer testified.

Peterson, 34, has been charged with an open count of murder and is being held at Kalamazoo County Jail. He was denied bond at his arraignment earlier this week.

He is scheduled for a preliminary examination hearing on evidence against him Nov. 6 before Kalamazoo County District Judge Paul Bridenstine.
